3. Click to preview the light source
Verify there is a strong, focused peak at 0 nm. If the peak is missing, weak, or out of
focus, verify the light source is turned on as well as the system is configured
properly. Acquire another image.
4. Click the button associated with the grating for which the offset is
being calculated. LightField calculates and displays the new offset value, in steps, in
the Calculated column with the corresponding wavelength error, in nm, next to it.
5. Click to clear the set of offset values that have just been calculated.
If desired, the offset may be manually fine-tuned using the four Manual
Adjustments arrows (« < > ») provided.
6. Click to accept the calculated offset value, apply it to the system, and
store the new value in the spectrometer’s EEPROM.
